Shoe upper



FIG. 1 is a front perspective view of a shoe upper showing my new design;

FIG. 2 is a side view thereof; and,

FIG. 3 is second front perspective view thereof.

The broken lines immediately adjacent to the shaded area represent unclaimed boundaries of the design. The broken lines within the shaded area represent unclaimed features of the design. The six unshaded regions within the shaded area that are demarcated by broken lines form no part of the claimed design. The broken lines showing the remainder of the shoe are for environmental purposes only and form no part of the claimed design. The contrast in shading represents a contrast in appearance only and does not represent any particular color, material, texture or finish.
